    摘要： On a slider which is pressed by a carriage to follow the movement the carriage while moving up and down on a base in accordance with the movement of the carriage, a cap is provided swingably through a support frame urged against a recording head by a spring or the like so that only one of its corners projects out at the time of non-capping. The cap moving up in accordance with the movement of the carriage, first, comes into contact with a nozzle plate of the recording head, and then expands the contact region gradually until it contacts with the whole of the nozzle plate. Therefore, pressure is concentrated in the contact free region partially so that the cap becomes familiar to the nozzle plate from its one corner and expands the contact region to make sealing finally.

    摘要： A pump unit and corresponding method for applying negative pressure to a capping device to prevent clogging of a nozzle opening in an ink jet printer includes a frame having a supporting surface on which a pump tube is disposed. A plurality of gears which are driven by a motor of the ink jet printer are disposed in the frame. A plurality of pulleys are rotatably mounted to one of the gears for applying a pressure to the pump tube to thereby generate a negative pressure in the pump tube. The maximum contact region between the pulleys and the tube in the pump frame is selected to be smaller than 180.degree. to allow for the load applied to the tube by the pulleys to be essentially constant. Damper sheets are economically disposed in the frame to position the pulleys to contact the tube when the gear on which the pulleys is driven in a certain direction. The tube is lead out of the frame in a manner so that at least one half of the tube is bent at right angles at a position where the tube separates from the tube supporting surface and is fixed in a slot formed in the pump frame. Accordingly, the frame space facing the tube supporting surface is used effectively, and the tube can be freely lead to a connection point external of the pump frame.

    摘要： An ink jet type recording apparatus in which two recording heads are mounted on one and the same carriage in such a manner that their spatial relationship is fixed, and the heads are positively sealed simultaneously by a capping means. A first cap member 13 adapted to seal the first recording head is provided near an end, proximate to the printing region, of a slider 20, which lifts a base stand according to the movement of a carriage. The first cap member has an air communication hole, and an ink suction hole therein. In addition, a second cap member 14 adapted to seal the second recording head is mounted through elastic members 74 and 75 on the slider 20. The second cap member 14 has an air communication hole, and an ink suction hole therein. The end of the slider 20, proximate to the non-printing region, is supported with an arm 30 which is elastically pressed vertically upwardly of the printing region. The two cap members are fixedly spaced from each other. The first cap member, is slidingly fitted over the first recording head by means of elastic members 31 and 32, thereby making sealing contact with the first recording head; while similarly the second cap member, is slidingly fitted over the second recording head by means of elastic members 74 and 75 interposed between the second cap member and the slider, thereby making sealing contact with the second recording head.

    摘要： An ink jet recording apparatus includes an ink consumption operating unit that adds a quantity of ink to be discharged by suction processing as a quantity of ink consumed before performing the suction processing. The ink jet recording apparatus includes also a suction control unit that performs the suction processing after such addition. A remaining ink level is calculated by estimating a quantity of ink to be used in a large volume for sucking as a quantity of ink consumed, and, even if a power supply switch is turned off before the sucking operation is terminated, the calculated remaining ink level as a quantity of ink consumed is added to a consumption storage unit 33. As a result, a possible erroneous overestimation of the remaining ink level in an ink cartridge can be avoided.
